There are Wacom tablets that have a pressure range from 0 to 2047. These work without any problem in Linux.
But there are others with range from 0 to 1024 like all the Bamboo models (you can take a look to the file /var/log/Xorg.0.log and search fro MaxZ and see what value it has).
When using a Wacom in Linux that has a 1024 range for Pressure, to sculpt in blender the result is different than in Windows. The Linux driver has a bug at the moment.
Look to this image. In the top you see a comparison Windows vs Linux. In each one I draw first with Pressure unchecked and then with Pressure checked, trying in this last case going from very soft to hard pressure. You see windows reach much higher than Linux.
With a modification to a file in blender this different result than in windows can be fixed, as shown in the lower part of the image: Windows vs “Linux Fixed”.
